The invention relates to a carbonization-resistant waterproof slurry. The carbonization-resistant waterproof slurry is a double-component organic/inorganic material composite slurry, and comprises cement, quartz powder, redispersible latex powder, cellulose ether, a super plasticizer, a water repellent, a carbonization inhibitor, an emulsion, water, an antifoaming agent, and an antiseptic. The carbonization inhibitor is prepared by modifying a mixture of calcium oxide and calcium montmorillonite powder with mineral oil, and effect controlling on release of active ingredients of the carbonization inhibitor can be realized via modification, so that compact and uniform waterproof layers are formed from the surface to the internal part of a coating thin layer, moisture penetration is prevented with high efficiency, excellent carbonization resistance and water resistance are obtained, and service life of the coating layer and concrete protection term are prolonged. Compatibility of the carbonization-resistant waterproof slurry with inorganic materials such as cement is excellent, and excellent carbonization resistance and water resistance can be obtained by a functional thin layer with a thickness of 1 to 2mm.
